Do you really want the ability to perhaps accidentally (and easily) overload a charging circuit and just rely on its breaker to prevent overheating/damaging its insulation?
Teslas may have their issues, but one that I have NOT heard about is their OEM EVSE thinking more current is available to pull from the circuit than is actually there.
One EVSE that is adjustable is the GE Durastation, but it does so via jumpers inside the case. So you have to open it up to change how much it can draw, so it can't accidentally switch to a higher draw. I do agree with you that units that do so via an app (JuiceBox for example) might be asking for trouble.

Relying on empty breaker slots as an indication of unused capacity is a lot like relying on unused checks as an indication of how much money is left in your checking account.
FWIW I still have two full-size slots still unused in my 125 amp panel, but per my electrician my 30 amp circuit for the EVSE has it "maxed" out in capacity.
